Terry J. Reedy <tjre...@udel.edu> added the comment:

The doc for literal_eval says "evaluate ... a string containing a Python 
literal or container display."  To me, ' 1' qualifies, just as it does as an 
expression for eval().

The exception comes from parsing raising IndentationError with leading 
whitespace even when the mode is 'eval' rather than 'exec'.  This surprised me. 
Eval() gets strips the beginning of the string before it is parsed.  If parsing 
remains as is, I agree that doing the same for literal_eval strings.  But why 
should not parsing remove indents for 'eval' mode?
